We have a collection of 11 gifts that are completely over-the-top, ranging from the world’s largest tin of caviar to a private jet tour around the globe.

They’re just as lavish as the millionaire in your life.

Set them up on a ride with Keanu Reeves.

The KRGT-1 is the first bike made by Arch Motorcycle, the company founded by Keanu Reeves and Gard Hollinger in 2014. The limited-edition performance bike comes with a 124-cubic-inch twin engine, special racing-inspired trim, and performance suspension.

This package, which we saw on Neiman Marcus' Fantasy Gifts guide, comes with a two-day ride down the California coast, hotel and airfare included. Joining you will be Reeves and Hollinger themselves.

Get them their own billionaire toy.

The Quadski XL is an all-terrain vehicle that can instantly transform into a watercraft and can travel up to 45 miles per hour on both water and land.

Salesforce CEO Marc Benioff reportedly plays around with one while vacationing at his $12.5 million Hawaiian estate. He also recently gave two Quadskis to the San Francisco Police and Fire Departments as a gift, apparently because he thought they would be helpful for water rescues.

Splurge on the world's largest tin of caviar.

French caviar purveyors Petrossian have created only 50 of these 22-pound tins of caviar. Each tin, which is about the size of a tire, is filled with Ossetra caviar, which is the most expensive variety of the delicacy.

The caviar is hand-selected by a member of the Petrossian family, generally considered to be the worldwide leader in caviar distribution.

Send them off on a year-long private tour around the world.

VeryFirstTo has a package they're calling 'The Four Jet Tour,' a year-long tour by private jet.

The gift includes a ticket on four of the most exclusive private jet tours in the world: 'Timeless Discoveries,' a 24-day itinerary planned by the Fours Seasons; 'Following Caravaggio,' a trip through Italy arranged by Private Jet Tours for art lovers; 'Equatorial Explorer,' a trip by Captain's Choice that brings travellers to Peru, Easter Island, and the Galapagos; and 'Islands, Savannahs & The Amazon,' Abercrombie & Kent's private jet tour to some of the most remote places on earth.

Make the car lover's dream come true.

VeryFirstTo is offering the gift of a test drive with a different supercar every week for a whole year. The giftee will get the chance to borrow one of a long roster of luxury cars -- the Ferrari 458 Spider, McLaren MP4 12C, and Lamborghini Aventador LP700, to name a few -- for a week at a time.

Treat them to an extravagant timepiece that is both stylish and functional.

The 'Type 3' watch by Ressence isn't for everyone. Rather than typical watch hands, it has separate discs that rotate according to the hour, minute, second, and day of the week, meaning its appearance is always changing.

Buy them their own island hideaway.

For the more adventurous of the 1%, finding your beach can sometimes mean buying your own. A private island is the perfect purchase for a billionaire who's looking for both isolation and adventure, as most islands will require some kind of construction work.

Crawl Caye, located about 26 miles off the coast of Belize City, can be had for less than $4 million.

Send them on the trip of a lifetime.

Space enthusiasts will love this twofold gift, which we spotted on Neiman Marcus' annual Fantasy Gifts list. In 2016, the buyer will get to go behind the scenes of a test flight with World Views, a company that is planning balloon rides to nearspace, more than 100,000 feet above the Earth's surface. You'll get a three-night stay at the Miraval Resort in Tucson, Arizona, and a tour of World View's facilities with CEO Jane Poyter.

In 2017, you'll get to take a ride in the luxury pressurised balloon, hundreds of thousands of feet off the ground.
